摘要: 黄嘴白鹭(Egretta eulophotes)是全球性受威胁鸟类。2005年7月, 我们在浙江五峙山列岛对黄嘴白鹭的巢位
选择进行了研究, 共测量了74个巢。研究发现, hm2的馒头山小岛上, 黄嘴白鹭的巢呈聚集性分布, 平均巢
cm, 最小巢间距为15 cm。黄嘴白鹭对巢位具有明显的选择性, 优先选择在灌丛, 尤其是那些相对较
高的灌丛(高于50 cm)下营巢, 其次是较低的灌木(低于64 cm)内部和草丛上。多数巢存在遮蔽物。避风和遮荫是黄
嘴白鹭巢位选择的主要要求。台风是决定五峙山列岛黄嘴白鹭巢位选择的最主要因素, 而高灌木的数量直接影响
五峙山列岛黄嘴白鹭的繁殖成功和今后的资源状况。

Abstract: The Chinese egret (Egretta eulophotes) is a globally endangered species. During July in 2005, we
studied nest selection of Chinese egret in Wuzhishan Archipelago of Zhejiang Province. A total of 74 nests
were recorded. The results showed that the nests of Chinese egrets were aggregated in space on Mantoushan
Islet ( hm2) with an average distance of cm between nests, and a minimum of 15 cm. Chinese
